Stand-up comic and film actor Gad Elmaleh is not only considered the funniest person in France, but he's also dating Monaco's Charlotte Casiraghi, the stunning royal granddaughter of the late Princess Grace Kelly. And Casiraghi is expecting their first child together later this year.

Virtually unknown in the U.S., Elmaleh, 42, was actually in Woody Allen's Oscar-winning Midnight in Paris, as the misguided Détective Tisserant.

Starting Friday, American audiences will have the opportunity to see him again, this time in his starring role in the financial thriller Capital, opposite Gabriel Byrne and directed by Oscar-winning French director Costa-Gavras.

Here are five things to know about the Moroccan-born celebrity, who recently sat down with PEOPLE.

New York-born Santo Domingo, 29, who has a 5-month-old son, Sacha, with the second-in-line to the throne, wore a full-length Missoni gown with three-quarter-length sleeves and opted for flat silver sandals instead of heels for the late-morning ceremony in the grounds of the Prince's Palace, Hello! magazine reports.

After PEOPLE reported that her son Andrea Casiraghi is set to tie the knot with his fiancée, South American heiress Tatiana Santo Domingo, on Aug. 31, sources confirm that the Princess's daughter, Charlotte Casiraghi, is expecting her first child with French comedian and actor Gad Elmaleh before Christmas.

The good news doesn't end there: Charlotte, 27, and Morocco-born Elmaleh, 42, are also engaged and plan to wed this fall in a private ceremony.

Add another royal event to your calendar: Monaco's Andrea Casiraghi, the son of Princess Caroline and grandson of the late Princess Grace, will marry fiancé Tatiana Santo Domingo later this month, sources confirm.

"The wedding will occur on Aug. 31," a spokesperson for Monaco's Pink Palace tells PEOPLE. "It will be a private ceremony."

The couple, who have dated for seven years and have a son, Sacha, born last March, were schoolmates together at Paris's Lycée Fontainebleau.

They were introduced by Casiraghi's sister Charlotte and have been engaged since July 2012.

Princess Caroline of Monaco is a first-time grandmother, Monaco's Pink Palace announced on Friday.

"The Princess of Hanover and Madame Vera Santo Domingo have the joy to announce the birth of their grandson, born on March 21, 2013," a Palace statement said. "Both mother and the child are doing well."
